Built from steel, this go\/no-go style precision tool maintains a tolerance of 0.0002 inches, making it appropriate for quality control checks in production and job-shop environments. Machinists, toolmakers, and quality technicians use plug gages like this one to confirm that drilled, reamed, or bored holes fall within specified tolerances before parts advance to assembly or final inspection.\u003c\/p\u003e\u003cp\u003eThis plug gage is suited for use in precision machining, metalworking, and manufacturing inspection settings where hole diameter verification is part of a standard quality process. It is appropriate for both in-process checks and final inspection on steel, aluminum, and other machined workpieces. The compact size and steel construction make it a practical bench tool for inspection departments and floor-level quality checks alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNominal measurement diameter of 0.761 inches for direct hole verification\u003c\/li\u003e\n\u003cli\u003eClass ZZ Plus tolerance rating of 0.0002 inches for reliable go\/no-go inspection\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and dimensional stability under shop conditions\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.2 pounds for easy handling at the bench or on the floor\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging suitable for individual tool replacement or kit supplementation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use plug gage for any application requiring inspection of a 0.761-inch nominal inside diameter to Class ZZ Plus tolerances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlug gages are hand-held precision instruments and do not require mechanical installation. Before use, clean the gage and the hole being checked to remove chips, coolant, and debris that could affect the measurement. Handle the gage carefully to avoid dropping or striking it, as impact can alter its calibrated diameter. Periodic re-calibration against a certified master is recommended to maintain traceability in regulated inspection environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter of Measurement\u003c\/strong\u003e: 0.761 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 29-761-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720993014066,"sku":"29-761-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/256e1d540a00805c28e94da9ed08f54c.jpg?v=1788571997","url":"https:\/\/voomisupply.com\/products\/spi-29-761-4-class-zz-plus-plug-gage-0-761-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
